Question

the frequency of a strong yellow line in the spectrum of sodium is 5.09*10¹⁴ sec-1? calculate the wavelength of the light in nm​

Answer 1

Welcome Students,

◆ Answer -

λ = 589.4 nm

● Explaination -

# Given -

c = 3×10^8 m/s

ν = 5.09×10^14 /s

# Solution -

Wavelength of the light is calculated by -

λ = c / ν

λ = 3×10^8 / 5.09×10^14

λ = 5.894×10^-7 m

λ = 589.4×10^-9 m

λ = 589.4 nm

Hence, wavelength of the light is 589.4 nm.

Best luck...
